Hello,

I've recently moved into the world of Polk and so far am very impressed. I picked up an RM10 System which included a PSW 10 Sub. I've currently got the sub just to the right of my AV cabinet on the floor. Sound is very good but I do notice that I can localize the sub to the right side of the room probably due to the crossover being set at 100hz. One of the local retailers has the PSW 10 on sale for $132.00 and I am wondering if it would be worth it to add a second one to the left side. Does two subs create any problems? If I add the second sub do I calibrate them to be exctly the same?

Thanks,
